Which technology abstracts hardware resources to enable multiple operating systems to run on a single machine?

• A. Cloud Carrier
• B. Virtualization
• C. Cloud Broker
• D. Cloud Provider

Answer: (B)

Virtualization abstracts hardware resources to enable multiple operating systems to run on a single machine. A hypervisor sits between the physical hardware and the guest systems, slicing up CPU time, memory, storage, and I/O so each virtual machine has its own allocated resources. Each VM runs its own guest OS, with its own kernel and drivers, and remains isolated from the others. This allows different operating systems to coexist on one physical host without interfering with one another, maximizing hardware utilization and providing strong separation. The other terms describe roles in cloud computing rather than the mechanism for running multiple OSes on one host. They relate to delivering or coordinating cloud services across networks, not to abstracting a single machine’s hardware to support several operating systems.
